FreEnt Technologies, Inc. (FreEnt) proposes to design and develop a new type of radar for mapping debris trajectories through a fireball. The Radio Frequency (RF) based system is designed to ?see? through the explosive fireball, and collect data obscured to other sensors (i.e. optical, other RF sensors, etc.). FreEnt?s technique and system architecture will result in accurate fragment trajectory characterization with high spatial, temporal, and velocity resolution for mapping the trajectories of thousands of individual fragments. The system will be designed to meet ground testing requirements and provide debris and trajectory characterization in a hypervelocity impact or explosive event fireball environment. In addition, rapid data collection and special data processing will yield estimates of individual debris mass that, along with other system outputs, are needed to support critical hydrocode validations.
